Because We Love Children

Orange You Glad I Didn’t Say Banana?

We are studying fruit in botany these days. Yesterday, my third graders and I had a wonderful time exploring oranges.
We started by guessing what was in a closed bag (oranges, of course). Then each child estimated the weight.

When the bag of oranges were revealed, I asked the class: “If we know the weight of the whole bag of oranges, and we know, the number of oranges, how can we determine the weight of one orange?” Ahhh… long division in action.

I partnered the kids into pairs. While we played music, the kids rolled , then tossed the oranges, promoting friendship, cooperation, and fun.

Next: We studied our oranges:
geometry: What shape are oranges? (spheres) What other spheres can you think of? (balls, the Earth)
geography: We imagined the orange was the Earth. We found the stem of the orange. That was like the North Pole. We found the navel of the orange. That represented the South Pole. We took our oranges and rotated them in the same way that the Earth rotates.

We looked at real globes and found the Equator. We drew the Equators on our oranges. We named the Northern and Southern Hemispheres We noted that we live in the Northern Hemisphere. We found the International Date Line on the Globes. We drew it on our oranges and discussed the Eastern and Western Hemispheres.

We drew rough shapes of the continents.

geology We peeled an orange and compared the peel to the Earth’s crust.

We also explored orange buoyancy. We found that an orange will not float in a large, shallow, tub. I asked the class how we could get the orange to float. They said, “Add more water!”

“That might work,” I agreed. “But we can make it float without changing the amount of water.”

“Hollow out the orange!” the students suggested.

“That could be fun. And it might work,” I said. “But we don’t have to change anything about the orange to get it to float. What do we need to change?”

“Put it in a different container!’ the class decided.

With that, I poured the water out of the shallow tub and into a tall, cylindrical container. The orange floated!

We wrote orange adjectives, like: juicy, orange, sweet, round, fruity, bumpy, nutritious, and delicious.

Finally, we feasted on our oranges.

By the way, I do like bananas. But that is a blog for another day. 🙂
